/* HZN DayZ - site stylesheet.
   Hand-written (no framework) so the page ships as one small file with no build
   step and no CDN dependency.

   Visual language is a field comms terminal: near-black steel, hairline rules,
   square corners, and monospace for anything that is data rather than prose.
   Exactly one accent colour, used sparingly - if something is accented it is
   either live, interactive, or important. No gradients: they were the main
   reason the old design read as generic.

   The accent is sampled from the HZN mark (#1e88e6) so the logo reads as part
   of the interface. Text sits at #4ba3ef instead: the mark's blue is only
   ~3.6:1 on the panels, which fails WCAG AA for body-sized type. */
